ABSTRACT:
Sampling system and method for obtaining representative samples of aerosols in which the particulate concentration is greater than 10.sup.6 particles/cm.sup.3 comprising a sampling probe which operates in cooperation with a dilution system such that a sample of concentrated aerosol can be taken from the gas stream by the probe and almost simultaneously quenched and diluted to a temperature and concentration, respectively, which is acceptable to conventional measuring instruments.
